The current research aims to study the relationship between production capacity and profitability after including the moderator role of investment in inventory, especially the main reason for investment in fixed assets as a measure of production capacity is to make profit. If the organization expands the industrial base by increasing production capacity to the limits It is not possible for any organization to continue without building its production capacity associated with investing fixed assets such as buildings, machinery, equipment, land, and cars. Profits can be generated by investment in these assets to ensure profitability in the long term and inventory investment is another determinant of the profitability of the organization in addition to the expected impact of production capacity and growth, especially that the efficient investment in the inventory reduces many of the costs associated with it and thus increase the profitability of the organization, which calls for studying the relationship between production capacity and profitability with the inclusion of the moderator role of the efficiency of investing inventory. The research has based on the secondary data published in the Investor Guide issued by the Iraqi Stock Exchange for a sample of (16) industrial companies selected by means of the intentional sampling method for the period (2006-2015). The variables were then measured and analyzed quantitatively and statistically according to a research horizon combining two methods of analysis; spatial variation (companies) and temporal variation (duration of research) . The study, after conducting the required analyzes of the sample data and testing the hypotheses of the research reached to a number of conclusions that were formulated after the intellectual reasoning of the results summarized in their content that the inventory plays a moderator role or modified the strength of the relationship between the production capacity and profitability of the studied Iraqi industrial companies.

In this paper, the classical nonparametric estimations are used to estimate reliability function for k-out of-n system, series system, and parallel system by using three different methods: Kernel estimator method, Kaplan-Meier estimator method, and product limit estimator method. These functions are compared to Bayesian nonparametric reliability estimator which is proposed by Ferguson in 1973 and dubbed the “Prior Dirichlet Processes”. To choose a better method for estimation, it has been used a simulation procedure for different sample sizes of size (14, 30, 60, and100) using Integral Mean Square Error (IMSE) for comparison. The results indicate that it is better to use the classical method with k-out of-n system and parallel system, whereas for series system it is better to use Bayesian method for small samples of size (14, and 30) and the classical method for big samples size of (60,and100)

In recent years, there has been a notable increase in the proliferation of the falsification of academic certificates in some countries, such as Iraq. The act itself is a crime punished by the law, as it is considered to adulterate the truth, the acquirement of an academic title with the only intention of defrauding and cheating with an official certificate (the title). This practice has become a social phenomenon that preoccupies several sectors of the law; The experts in administrative law are immersed in finding ways of discouragement in order to reduce this type of crimes. In addition, experts in criminal law propose the search for severe sanctions for this phenomenon. On the other hand the sociologists are immersed in the search of the psychological reasons that lead to commit this type of acts. Counterfeiting is a crime that seriously violates the authority of the state and its material interests and consequently damages the interests of individuals and the confidence of the people in its administration and is one of the manifestations of financial and administrative corruption. Diagnosing only the phenomenon of the problem without applying a legal deterrent has become a mockery and has given rise to expressions of revulsion. For all this, it is expected that administrative and penal legislation will take action in this matter. This study focuses on highlighting the laws on this subject in particular from some Arab countries, including Iraq, to analyze them extensively and compare them for the purpose of developing a treatment plan and seek solutions to these illegal practices. The results and conclusions of the study will be presented.

Terrorism has become a criminal phenomenon that threatens all humanity, and drag it to the primitive ages, because these crimes involve the brutality , violence, barbarism , a clear violation of positive laws, humanitarian values and divine laws. Despite the cover up in religious values, commissioning of terrorist crimes under the auspices al-Sharea and implementation of its provisions , religion is innocent of the terrorists and their crimes. As the world today starts to understands beyond any doubt possibility , the real danger lies in thought and ideology adopted by terrorism. Perhaps the most dangerous is the excommunicating ideology that terrorists rely upon in the commission of terrorist crimes. This requires to face this thought and drain its resources. In this study we address Legal treatment of excommunicating ideology connected with the extremist terrorist groups , and highlight the historical roots of this ideology , the history the groups adopted and the political systems that support it. The study attempts to draw an outline of substantive and procedural "Criminal Policy" to be adopted, which would achieve effective legal confrontation of excommunicating ideology connected with the extremist terrorist groups.

The last quarter of the twentieth century witnessed a fundamental shift in the vision of institutions of higher education (university) and direction of education and research in response to the changes and the many developments such as globalization and the explosion of knowledge, information and high technology. Universities are becoming a way for the progress of societies and the standard for nations promot as academic centers producing knowledge and on help exploiting scientific energies and technology available to serve the community. During the recent three decades, young people in Iraq were excluded from education and the labor market because of their poverty and isolation from the mainstream of development and deprived wholly or partly, from their rights. Although education in Iraq is free from kindergarten to university, but most families want to get a better level and quality of education for their children. This interest commensurates with the improvement of living standards, hence the in education, health and standard of living level, which is the engine of human development.
The research has focused on the provisions of the link between higher education and economic and social development plans, plans through its contribution in the formation of capital, knowledge and human resources development, adapted to the requirements of development and the needs of the labor market and the number of qualifying in various scientific and professional disciplines to the community of human resources, and provide the community eligible frameworks highly qualified to lead carry out the responsibility for development
The first section dealt with the conceptual framework of the university and human development by identifying the university (University of Diyala) where it dealt with a historical background about it and the university concept and the concept of human development and its most important indicators and tackling the most important challenges facing education. , While the third topic focused on the development of a vision for the future of the compatibility between education and the requirements of the labor market in Iraq.

Iraq today is facing big challenges which affected the government performance in a negative way . Corruption has serious negative effects on the efficiency of implementing the development programs . Among these challenges facing Iraq is the spread of political corruption , in addition the lack of intention concerning fighting corruption and the lack of professional concerning leadings position . Iraq also suffers from the failure of banking system and its inability to prevent money laundering , and the lack of cooperation and coordination between public institution ,and the authorities in charge of fighting corruption .
We need a real reform to fight corruption , institutional framework to corruption and accelerate economic development. This study is to shed light on the fight against corruption to alleviate the economic and social effects and propose solutions to fight corruption in order to boost economic development in Iraq.

This paper proposed a small size and efficient square-shaped printed spiral coils (PSCs) at 13.56 MHz to be used for implantable biomedical devices. Detailed modeling of PSCs is presented. A design methodology has been applied to theoretical closed-form equations using MATLAB to optimize the wireless link of a 12×12 mm2 implantable coil example with 10 mm relative distance. All results are validated with the simulation using an electromagnetic field solver HFSS 14.1. Also, the PSCs has been implemented for verification using FR4 printed circuit board. The results show that optimized coil pairs achieved efficiency up to 80% at face to face relative distance of 10 mm in the air.

The modeling of the lubrication of human ankle joint has been considered in this present research. Many parameters were carried out such as joint geometry parameters as (minimum film thickness h, radial clearance c, Eccentricity e), lubricant parameters as (synovial fluid viscusity μ, couple stress property η) and cartilage matrix parameters as (Ratio of microstructure size to pore β, Permeability of the cartilage ϕ, Porous layer thickness H). The effects of these parameters on the synovial fluid velocity, pressure in the porous region, load carrying capacity per unit length of the bearing and the coefficient of friction were investigated. The model starts from the theory of boosted lubrication for the human articular joints lubrication and takes into account the fluid transport across the articular cartilage using Reynolds equation and modified Darcy’s equation. The results show that the pressure increased with increasing the couple stress length and the eccentricity ratio parameters. The synovial velocity profile was changing from Newtonian at (l*=0.0) to non-Newtonian profile as increasing the couple stress length. Finally the coefficient of friction increases with decreasing the eccentricity ratio and with increasing the joint radial clearance.

The effect of incident solar radiation ray’s penetration through glassed windows of duct - ventilated room enclosure air is investigated assuming constant solar intensity. The room is supplied with cold dry air through rectangular duct and the air is distributed through two grid ceiling fans located at the duct exit. The effect of fixed solar intensity penetration with variable fans rotational speed at specified time intervals is investigated upon the room temperature distribution and is simulated using the ANSYS CFX package. The results showed the variation in room temperature distribution at a specified time period (1, 2, 3 minutes) with increased fan speed becomes more efficient, also the transient room temperature distribution response to the solar radiation is significantly present in the simulation noticing fans effect on accelerating heat transfer rate through the domain.

In this research we introduced the definition of a map with period 3 on a ring Ɍ and on right ( left ) ideal Ῑ of Ɍ, then we prove that, when Ɍ is a prime ring with char (Ɍ)  2, and Ῑ  0, Ῑ is right ideal on Ɍ, if đ is a derivation with period 3 in Ɍ,then either đ=0, or u2=0 uῙ. Also we proved, when Ɍ is a domain with 1, and char (Ɍ)  6, If δ is a right generalized derivation on Ɍ with period 3, then δ is the identity map. Lastly, we define a map with Period 3 on near-rings, and gived results for prime left near-rings with maps acts as an anti-homomorphism (or homomorphism), with period 3, to obtain commuatative rings.

Data warehouse (DW) refers to a system architecture rather than a software product or application, and it is used to improve Information Technology (IT) infrastructure. However, the rate of its successful implementation is still low and most firms report failure to leverage the system for their goals. This paper provided a discussion of the results of the model based on Information System (IS) Success Model, particularly the relationship between quality factors and the net benefits obtained from the data warehouse system. Independent variables were selected to gauge service quality and relationship quality service, while the dependent variable measured the net benefits obtained from the system. The paper provided a background on data warehouse and successful implementation of data warehouse, as well as a description of the research model and proposed hypotheses inclusive of the affective factors. It provided a deep insight into the data warehouse success factors with the use of data warehouse success model that ultimately provided informed inferences for decision making regarding successful data warehousing implementation.
